I’ve been troubleshooting an odd issue with a G3X system equipped with a GEA24 EIS utilizing the stock Van’s resistance float fuel level sensors.
I’m hoping someone can share the voltages that register in the calibration page for full and empty for a similarly equipped plane.
By way of background, when I initially calibrated by RV-14A, my system derived the following data points:
Empty - 0.3 volts
Full - 2.21 volts
I calibrated every two gallons and, as expected, all of the data points followed the same trend: as the tank level increased, the measured voltage increased.
At some point between pre flight for the first flight and start up for the second flight, the system seems to have inverted the readings. Now, as the tank level increases, the voltage decreases. Curious. Very curious.
I’ve been in contact with Garmin and have done extensive troubleshooting including using a dummy circuits, a VOM, etc. Garmin generously provided a replacement unit under warranty, but that did not resolve the problem.
Please let me know the following for your system:
Calibrated voltage at 0 gallons
Calibrated voltage at 25 gallons
When fuel level increases, does the voltage measured on the calibration screen consistently increase or decrease?
Thanks in advance for sharing your information.
